I am a first year Math major in the university, this summer I want to self study and go over some specific subjects.
Firstly, can someone can give a suggestion for a detailed book/article about the construction of Real numbers? I felt like we discussed this subject briefly in my first Analysis course, and want to know more about it.
Secondly, I am planning on studying Set theory , and need a good book for self study. (Undergraduate)
Lastly, I need a good suggestion for Discrete math (undergraduate) text book for self study.
If by experience someone knows good books, I would be happy to hear your suggestions! Appreciate the feedback!
